. PLEASURE-CAR-.

, Specification of Letters Patent.

Application filed October 30,1905. Serial No. 285,062.

.novel construction and combination of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is'a side elevation of the pleasure-car. Fig. 2 is a top plan thereof, and Fig. 3 is a vertical cross-section on line 3 3 of Fig. 1.

The present invention isa qualification of the construction of pleasure-car shown and described in United States Letters Patent No. 7 93,114, issued to me under date of June 27, 1905, and has for its objects to impart a novel and distinct movement to the car which will result in producing a correspondinglyexhilarating and novel sensation on sengers occupying the same.

A further object is to PIOduce an easilythe pasrunning car and one whose travel is attended with a minimum amount of friction, all as will more fully appear from a detailed description of the invention, which is as'follows: Referring to the drawin s, CC represent two cars of any approved esign or pattern, the cars being disposed parallel'to one another and jointly occupying the space between the lanes of rotation of the opposite wheels W of what may be considered the front and rear trucks. The wheels of each truck are connected by a compound crank-arm A A,

the terminal crank-pins 1 1 of whose compo-' nents extend horizontally in opposite directions and are coupled to the ad acent wheels on opplosite sides of'the centers of the respectivew eelsthat is to say, on opposite sides of their common axis ofarotation. The center of rotation of the crank-arms corresponds to Y the axis of rotation of the Wheels, the vertical members of the individual crank-arms being connected at such center by a cylindrical portion 2, which forms a bearing for the longitudinally-disposed central coupling-pole 3, connectin the front and rear trucks. The rear end 0 this couplin -pole is formed into or carries a latform P or the operator, who has control 0 the grip G, by which the cable 4. is

Louis, State of Missouri, have invented,

.is apparent, of course,

seized or from which said cable is released, as occasion demands. The trucks run on suitable railsR, between which the cable 4 is centrally disposed.

The horizontal members 1 1, forming the crank-pins of the components of the respective compound crank-arms, are loosely couled to the under sides of the juxtaposed cars C, which they support, the crank-arms being initially so adjusted that the crank-pins of the components of the compound crankarms of each truck are on o posite sides of the axes of rotation of the w eels of the respective trucks, so that when one pair of Patented May 15, 19oe. 1

crank-pins are elevated or are above the plane of the axes of rotation of the wheels the other pair is below said axes. The result is that when one car occupies its highest position the other car is occupying its lowest position, Fig. 3, and as the wheels revolve the cars move up and down alternately, the nature of the motion for each car being on the order of the connecting-rod which couples two adjacent driving-wheels on a locomotive that is to say, the movement is a 1011- gitudinal or horizontal reciprocating one, as

well as vertically reciprocating, the cars always moving parallel to themselves for the longitudinal or horizontal movement. The wheels are provided with outwardly-projecting axial bosses or hubs 5, which are loosely embraced by the 100 s 60f an oblong frame 7 coupled to the plat. orm P. The frame and platform (and coupling-pole) are thusbound together, so as to result in a rigid construction, the frame at the same time resisting any tendency of the truck-wheels to spread. It

that so far as the sensation produced b the movements of the cars is concerned the trucks need not neces-. saril have to run on rails, but may be susen ed above ground so long as rotation is imparted to the wheels in any suitable mechanic al manner.

Having described claim is.

1. In a pleasure-car having'afront and a rear truck, wheels for said trucks, a commy invention, what I pound crank-arm comprising two component wheelsfand a compound crank-arm between opposite sides of their common axis of rota-' them having the crankins of its component crank-arms coupled to t e wheels on opposite sides of the common axis of rotation of the wheels substantially as set forth.

3. In a pleasure-car, a front and rear truck, Wheels for the trucks, a compound crank-arm comprising two com onent crank-arms connecting the wheels of e'ach truck at points on own, the crank pinsof the crank-arms on one side of the vehicle being coupled to the adja. cent Wheels above the plane of their axes of rotatiomwhile the crank-pins on the opposite side are coupled to their wheels below said plane, and cars mounted on the crank-pins on' opposite sides of the vehicle, whereby upon rotation of the truck-Wheels the car on one side will be up while that on the opposite side is down, and vice versa, the parts operating those on the other side are on the opposite side of said plane, cars mounted on the crankpins of the arms at opposite ends of the respective trucks, cylindrical connections between the centers of rotation of the component members of the com ound crank-arms, said centers being dispose on the axes of rotation of the truck-wheels, a coupling-pole connecting said cylindrical connections and a latform at one end of the pole, substantial y as set forth.

5. In a'pleasure-car having afront and rear truck, a coupling-pole connecting the trucks, and a frame connecting the coupling-pole with the wheels of the trucks, substantially as set forth.

6. In a truck for cars, a pairof wheels, anda compound crank-arm composed of two component arms extending in opposite directions and united at their common center of rotation, the ends of the component arms being coupled to the wheels ofthe truck at points eccentric to their axes of rotation,

substantially. as set forth. In testimony whereof I afiix my signatur in presence of two witnesses. 1 JAMES D. WALSH.
